| Vi has two modes insertion mode and command mode. The editor begins in command mode, where the cursor movement and text deletion and pasting occur. Insertion mode begins upon entering an insertion or change command. [ESC] returns the editor to command mode (where you can quit, for example by typing :q!). Most commands execute as soon as you type them except for "colon" commands which execute when you press the ruturn key. |

| Almost all deletion commands are performed by typing d followed by a motion. For example, dw deletes a word. A few other deletes are: |
| x | Delete character to the right of cursor |

| X | Delete character to the left of cursor |
| nX | Deletes previous n characters; omitting n deletes previous character only |

| "np | Retrieves the last nth delete (last 9 deletes are kept in a buffer) |
| "1pu.u. | Scrolls through the delete buffer until the desired delete is retrieved (repeat u.) |
| Like deletion, almost all yank commands are performed by typing y followed by a motion. For example, y$ yanks to the end of the line. Two other yank commands are: |
| yy | Yank the current line |
| :y | Yank the current line |
| nyy or nY | Places n lines in the buffer-copies |
| yMotion_cmd | Copies everything from the curser to the Motion Command (e.g., yG would copy from current position to the end of the file, and y4 would copy to the end of the fourth sentence) |
| "(a-z)nyy or "(a-z)ndd | Copies or cuts (deletes) n lines into a named buffer a through z; omitting n works on current line |
| The change command is a deletion command that leaves the editor in insert mode. It is performed by typing c followed by a motion. For example cw changes a word. A few other change commands are: |
| C | Change to the end of the line |
| cc or S | Change the whole line until ESC is pressed |
| xp | Switches character at cursor with following character |
| stext | Substitutes text for the current character until ESC is used |

| << or >> | Shifts the line left or right (respectively) by one shift width (a tab) |
| n<< or n>> | Shifts n lines left or right (respectively) by one shift width (a tab) |
| <Motion_cmd or >Motion_cmd | Use with Motion Command to shift multiple lines left or right |
| p | Put after the position or after the line |
| P | Put before the poition or before the line |
| "(a-z)p or "(a-z)P | Pastes text from a named buffer a through z after or before the current line |
| Named buffers may be specified before any deletion, change, yank or put command. The general prefix has the form "c where c is any lowercase character. for example, "adw deletes a word into buffer a. It may thereafter be put back into text with an appropriate "ap. |
| Named markers may be set on any line in a file. Any lower case letter may be a marker name. Markers may also be used as limits for ranges. |
| mc | Set marker c on this line |
| `c | Go to beginning of marker c line. |
| 'c | Go to first non-blank character of marker c line. |
| /string | Search forward for string |

| ?str | Finds in reverse for str |
| :set ic | Ignores case when searching |
| :set noic | Pays attention to case when searching |
| :n,ms/str1/str2/opt | Searches from n to m for str1; replaces str1 to str2; using opt-opt can be g for global change, c to confirm change (y to acknowledge, |
| & | Repeats last :s command |
| :g/str/cmd | Runs cmd on all lines that contain str |
| :g/str1/s/str2/str3/ | Finds the line containing str1, replaces str2 with str3 |
| :v/str/cmd | Executes cmd on all lines that do not match str |
| , | Repeats, in reverse direction, last / or ? search command |
| The search and replace function is accomplished with the :s command. It is commonly used in combination with ranges or the :g command (below). |
| :s/pattern/string/flags | Replace pattern with string according to flags. |
| g | Flag - Replace all occurences of pattern |
| c | Flag - Confirm replaces. |
| & | Repeat last :s command |

| \> | Matches end of word |
| ^ | Anchor - beginning of the line |
| $ | Anchor - end of line |
| \< | Anchor - begining of word |
| \> | Anchor - end of word |
| \(...\) | Grouping - usually used to group conditions |
| \n | Contents of nth grouping |
| \ | Escapes the meaning of the next character (e.g., \$ allows you to search for $) |
| \\ | Escapes the \ character |
| [A-Z] | The SET from Capital A to Capital Z |

| [A-Z][a-zA-Z] | In the first position, the SET from Capital A to Capital Z In the second character position, the SET containing all letters |
| [a-z]{m} | Look for m occurances of the SET from lowercase a to lowercase z |
| [a-z]{m,n} | Look for at least m occurances, but no more than n occurances of the SET from lowercase a to lowercase z |
| /Hello/ | Matches if the line contains the value Hello |
| /^TEST$/ | Matches if the line contains TEST by itself |
| /^[a-zA-Z]/ | Matches if the line starts with any letter |
| /^[a-z].*/ | Matches if the first character of the line is a-z and there is at least one more of any character following it |
| /2134$/ | Matches if line ends with 2134 |
| /\(21|35\)/ | Matches is the line contains 21 or 35 Note the use of ( ) with the pipe symbol to specify the 'or' condition |
| /[0-9]*/ | Matches if there are zero or more numbers in the line |
| /^[^#]/ | Matches if the first character is not a # in the line |
| Notes: 1. Regular expressions are case sensitive 2. Regular expressions are to be used where pattern is specified | |
| Nearly every command may be preceded by a number that specifies how many times it is to be performed. For example, 5dw will delete 5 words and 3fe will move the cursor forward to the 3rd occurence of the letter e. Even insertions may be repeated conveniently with this method, say to insert the same line 100 times. |
| Ranges may precede most "colon" commands and cause them to be executed on a line or lines. For example :3,7d would delete lines 3-7. Ranges are commonly combined with the :s command to perform a replacement on several lines, as with :.,$s/pattern/string/g to make a replacement from the current line to the end of the file. |

| :. | Range - Current line |
| :$ | Range - Last line |
| :'c | Range - Marker c |
| :% | Range - All lines in file |
